Step 2USB Connector
For the business card, the USB connector is actually the PCB itself. This saves on cost, looks great, and it keeps the card thin.
This connector will be a USB male "A" connector, which plugs into a USB female "A" port (the kind found on computers). First, measurements are taken from the USB port. I create an Eagle component with the dimensions (you need to create a library file first), and also place the pads. It is important to use pads because Eagle will remove the soldermask from pad areas by default. We need the pads to be exposed (not covered by soldermask) in order to make a connection with the USB port.
The created connector component is placed onto the PCB layout. The dimension layer must be a continuous line that follows the outline of the business card and the connector. The dimension layer is what the manufacture will follow when milling your PCB outline.
